extern "C" will work, but you still have to 'mess around' with .def files. The extern "C" stuff only makes the compiler use the unmangled name within the DLL.

Characters should generally be passed as strings.

Is that a sentence? If so, can you try again?

In the meantime ...

extern "C" does not cause the function names to be exported.
extern "C" does stop the name mangling from taking place on the function name.

I suspect what you are looking for is to prefix the function definitions with:

__declspec(dllexport)

That will instruct the compiler/linker to export the name in the same way that .def files do.
